Plumbing Fixtures We Install for Long Island Homeowners
Fixture installation is one of the most common requests we get from local homeowners. Our licensed plumbers handle everything from replacing a single bathroom faucet to installing all the fixtures for a full renovation. We make sure every connection is secure, and every valve works exactly as it should.
Faucet Installation
We install all types of faucets, including kitchen pull-down models, touchless versions, and widespread bathroom faucets. A proper installation means more than just tightening a few bolts. We handle the supply line connections and test everything thoroughly to make sure there are no slow drips that could damage your cabinets. Whether you bought the faucet yourself or need a recommendation, we are here to help.
Sink Installation
From deep farmhouse sinks to new bathroom vanities and laundry room basins, we handle the heavy lifting. We remove the old sink, prepare the opening, and ensure the new unit is secured and sealed properly. We handle the drain and supply line hookups so your new sink is ready for use right away.
Toilet Installation
A toilet that rocks or has a bad seal is more than just a nuisance. It can lead to hidden leaks that rot your subfloor over time. We install standard and comfort-height models, ensuring the wax ring and flange are perfectly set to prevent any future issues.
Bathroom Fixture Installation
Many homes in Nassau and Suffolk Counties still have original fixtures from the 1950s or 60s. If you are looking to modernize your bathroom, we can install a full package, including faucet, toilet, and shower valves, in a single visit. This is a great way to update your space with minimal disruption to your daily routine.
Kitchen Fixture Installation
The kitchen is the busiest room in the house, and the plumbing needs to be reliable. We handle sink and faucet installs, along with water line hookups for your refrigerator or dishwasher. Proper supply line work is essential here to prevent under-sink leaks, which are a leading cause of cabinet damage.
Showerhead & Shower Valve Replacement
If your shower has poor water pressure or the temperature is hard to control, the problem is often a worn-out valve or cartridge. Replacing these parts often requires going behind the wall, which is a job for a licensed plumber. We can also swap out old showerheads for newer, more efficient models to improve your morning routine.
Signs It Is Time to Replace Your Fixtures
Why Hire a Licensed Plumber for Fixtures?
It can be tempting to try a DIY installation, but hiring a licensed professional is the best way to protect your home. In New York, work that involves connecting to your water supply or drain system should be done by a licensed plumber.
We can often spot small problems, like a corroded shut-off valve, that a homeowner might miss. Plus, many manufacturers require professional installation to keep your warranty valid. At T.F. O’Brien, we provide that expert oversight for every job, no matter the size.
